1.3 Installation
For safety consideration, the UPS is shipped out from factory without connecting battery wires.
Before installation of the UPS, please follow the steps below to re-connect the battery wires.
Rack-Mount Installation
Caution! –DO NOT use the mounting brackets to lift the unit. The mounting brackets
are only for securing the unit to the rack.

Tower Installation
1.4 Setup
1. Select a proper location to operate the UPS
The UPS should only be operated indoors in a clean environment, away from windows and
doors. Place on a flat surface away from dust, humidity, high temperatures, liquids, gases,
or corrosive and conductive contaminants.
Maintain a minimum clearance of 100mm from the bottom of the UPS. Be certain to place in
a well-ventilated area; avoid blocking the fan’s air flow by maintaining a minimum clearance
100mm to the front and 300mm in the rear of the UPS.
Operate at or below a maximum altitude of 3000m for normal operation at full load.
2. UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
For 200/208/220/230/240VAC models: The power cord supplied with this UPS is detachable.
Note: Check if the site wiring fault indicator lights up in LCD panel. It will be illuminated when
the UPS is plugged into an improperly wired utility power outlet (Refer to Troubleshooting section).
Check if there is a circuit breaker against overcurrent and short circuit between the mains and
AC input of the UPS for safe operation. The recommended protection value as following:

but the UPS is not powered on until the power button is pressed for two seconds (see #7).
3. UPS output connection
There are two kinds of outputs: programmable outlets and general outlets. Connect non-critical
devices to the programmable outlets and critical devices to the general outlets. During power
failure, you may extend the backup time to critical devices by setting shorter backup time for
non-critical devices.
4. Communication connections
Communication ports:
USB port RS-232 port SNMP port
To allow for unattended UPS shutdown/start-up and status monitoring, connect the
communication cable one end to the USB/RS-232 port and the other to the communication port
of your PC. With the monitoring software installed, you can schedule UPS shutdown/start-up and
monitor UPS status through PC.
The UPS is equipped with an SNMP Network card. When installing either SNMP for advanced
communications and monitoring.
5. Network connection
Network/Fax/Phone surge port
Connect a single modem/phone/fax line into the surge protected “IN” outlet on the back panel
of the UPS. Connect another modem/fax/phone line cable to the “OUT” outlet and to the
equipment
6. Disable and enable EPO function
This UPS is equipped with EPO function. Pin 1 and pin 2 closed by default for normal UPS operation.
To activate, remove the protective metal plate and attach to your EPO system.
Note: The EPO function logic can be set up through the LCD settings. Please refer to program
16 in UPS setting for the details.

5
Powering on the UPS
NOTE: The battery will charge fully during the first five hours of normal operation. Full battery
run capability is not possible during the initial charge period.
Press the ON/Mute button on the front panel for two seconds to turn on the power to the UPS.
7. Install software
For optimal computer system protection, install UPS monitoring software to fully configure UPS
shutdown. Please follow steps below to download and install monitoring software.
1. Go to the website https://www.v7world.com/ups-downloads
2. Select ViewPower software for your operating system to download the software.
3. Follow the on-screen instructions to install the software.
1.5 Battery Replacement
Note: This UPS is equipped with internal batteries and only a trained technician should replace
the batteries.

3.6 Operating Mode Description
Operating mode
Description
LCD display
Online mode
When the input voltage is within acceptable range,
the UPS will provide pure and stable AC power to
output. The UPS also charges the battery in Online
mode.
ECO mode
Energy saving mode:
When the input voltage is within voltage regulation
range, the UPS will bypass voltage to output for
energy saving. The UPS also charges the battery in
ECO mode.
Frequency
Converter mode
When input frequency is within 40 Hz to 70 Hz, the
UPS can be set to a constant output frequency of
50 Hz or 60 Hz. The UPS still charges the battery
in this mode.
Battery mode
When the input voltage is beyond the acceptable
range or in power failure, the UPS provides power
from battery and the alarm will sound every 5
seconds.
Bypass mode
When input voltage is within acceptable range, but
the UPS is in overload, the UPS will enter bypass
mode or bypass mode can be selected through the
front panel. The alarm will sound every 10
seconds.
Standby mode
The UPS is off and not outputting power. The UPS
still charges the battery in this mode.
Fault mode
If a fault occurs, the ERROR icon and the fault code
will be displayed.

7. Instructions & Safety Warnings
7.1 Transportation
Transport the UPS system only in the original package to protect from damage.
7.2 Preparation
Condensation may occur if the UPS is moved directly from cold to warm environments.
The UPS system must be completely dry before being operated. Allow at least two hours
for the UPS system to acclimate to a new environment.
Do not install the UPS near water or wet, high humidity environments.
Do not install the UPS where it will be exposed to direct sunlight or near heat sources.
Avoid blocking ventilation holes in the UPS enclosure.
7.3 Installation
Do not connectappliances or devices which can overloadthe UPS system(e.g., laser printers).
Route cables to avoid stepping on or tripping over them.
Do not connect domestic appliances (such as hair dryers) to the UPS.
Connect the UPS system only to an earth-grounded shockproof outlet which must be
easily accessible and near the UPS system.
Use only VDE-tested, or UL-marked mains cables (e.g., the mains cable of your
computer) to connect the UPS system to the building wiring outlet (shockproof outlet).
Use only VDE-tested, UL-marked power cables to connect the loads to the UPS.
When installing the equipment, ensure that the sum of the leakage current of the UPS
and the connected devices does not exceed 3.5mA.
Temperature Rating - Units are considered acceptable for use in a maximum ambient
of 40°C (104°F).
FOR PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment
and shall be easily accessible.
CAUTION: The unit is heavy. Lifting the unit requires a minimum of two people.
7.4 Operation
Do not disconnect the mains cable on the UPS system or the building wiring outlet
(shockproof socket outlet) during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.
The UPS system features its own, internal current source (batteries). The UPS output
sockets, or output terminals block may be electrically live even if the UPS system is not
connected to the building wiring outlet.
To fully disconnect the UPS system, first press the OFF/Enter button to disconnect the
mains.
Prevent fluids and other foreign objects from entering the UPS.
The EPO and USB circuits are an IEC 60950-1 safety extra low voltage (SELV) circuit.
This circuit must be separated from any hazardous voltage circuits by reinforced
insulation.
7.5 Maintenance, service, and faults
The UPS system operates with hazardous voltages. Repairs may be carried out only by
